Industrial machinery often uses 480 Volt 3 phase services. The problem is Bitmain power supplies specify 240 Volts. One of the phase legs to ground is 277 Volts which is probably too much for the supply input to take. What is the solution? This is the page where I research that.
Possibility #1 – 2:1 step down transformer 480 to 240 Volts.
